For 2016, it mapped out a 398 trillion won budget, including a 10 trillion won supplementary budget, and came up with a 400.5 trillion won budget for 2017, surpassing the 400 trillion won level for the first time in its history.

At the same time, the country is expected to post a net 8.3 trillion won in tax revenue by the end of this year, considering that it collected an excessive 23.2 trillion won in taxes through October.

With the increase in government spending and tax revenue, the Ministry of Strategy and Finance said the national tax-to-GDP ratio will touch or top the earlier record of 18.9 percent, set in 2007, next year.

"On brisk tax collection, we see a record high in tax burden ratio," Deputy Finance Minister for tax and customs Choi Young-rok said in a briefing.

"For the 2016 budget, the rate was 18.9 percent and it will gain an additional 0.5 or 0.6 percentage point, given the supplementary budget. And if we add provincial taxes collected, which will be compiled later, the figure would surpass the 19.4-19.5 percent range."

Meanwhile, the finance ministry unveiled the follow-up to the tax code revision plan announced in July, focusing on bolstering corporate investments in new future industries and promoting fair taxation.

The ministry said tax credits of up to 30 percent will be given to companies that make research and development investments in 11 selected new industries, such as smart cars, biomedical technologies and renewable energy.

The government will also offer a 10 percent tax credit for facility investment into those areas, while movie and TV drama producers will get a 10 percent tax credit on production costs.

Taxation on financial income will be tightened as those who have a stake of 1 percent or worth 1.5 billion won in a listed firm will be subject to a transfer gain tax, down from the current 2.5 billion won. The ceiling will be lowered to 1 billion won in 2020.

Starting from 2017, the transfer income tax will be also imposed on gains from the equity linked warrant, a derivative that gives holders the right to buy or sell at an earlier-set price and date.

Added-value taxes imposed on purchases by mileage points will be removed, while foreigners will get a refund of up to 5 million won, up from the current 2 million won, when they buy goods at tax refund shops. ■
